This paper presents a heuristic approach to the short-term unit commitment problem. First, it divides the generating units capacities into three categories, then it establishes a rough 24 hour-generation schedule and finally, it performs the global optimization as an inference process. A prototype system is developed and tested on an IBM-386 personal computer using the C language. The ToolBook software is used to enhance the graphics capability of the package. The primary advantage of the proposed method is featured by its short processing time for each schedule as it schedules the generation unit commitment for a typical system in less than 2 seconds. The same system is examined by dynamic programming with an average running time of 20 minutes on an IBM 386 personal computer.
